Dust arrester and method for removing dust particles from air

Abstract

A dust arrester includes a housing with air inlet and air outlet, wherein the ambient air containing dust particles can be introduced into the housing via the air inlet and discharged from the housing via the air outlet. The dust arrester further includes a water trough placed in the bottom of the housing and a chaos effect generator including a nozzle and a material. The nozzle can spray water supplied from the water trough. The water sprayed interacts with the material to generate a chaos condition, so that the dust particles can be removed from the introduced air under the chaos condition.

Description

RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Application No. 61 / 267,970, which was filed Dec. 9, 2009.TECHNICAL FIELD[0002]The present disclosure relates to a dust arrester for air purification and a method for removing dust particles from air.BACKGROUND[0003]It is well known that air pollution is becoming an increasingly serious problem. A main source of air pollution is from construction and decoration projects in cities. Due to the inherent nature of construction and decoration engineering and urgent schedule that often requires various kinds of operations to be carried out within a limited space in a short time, the work sites of construction and decoration engineering are generally full of dust and undesirable odors. Therefore, not only the engineering staff at the working sites but also the neighboring residents will be exposed to and have to endure the poor environmental condition.

AI Technical Summary

Benefits of technology

[0007]This disclosure aims to provide a dust arrester that can avoid the above-mentioned defects existing in the prior art. Moreover, the examples herein further aim to provide a dust arrester and a method for removing dust particles from air in a high efficiency with simple structure at an affordable cost.

[0008]According to one embodiment, a dust arrester is provided, which includes: a housing with air inlet and air outlet, wherein the ambient air containing dust particles can be introduced into the housing via the air inlet and then discharged from the housing via the air outlet; a water trough arranged in the bottom of the housing; and a chaos effect generator including a nozzle and a material, wherein the nozzle can spray water supplied from the water trough, the water being interacted with the material to generate a chaos condition, so that the dust particles can be removed from the introduced air under the chaos condition.

[0009]According to an embodiment, the dust arrester creates an artificial chaos condition under the wind pressure generated by the extracted air. This kind of dust particle removing way is of high efficiency, and suitable for applications in construction and renovation sites or similar places. It can effectively trap the dust particles contained in the air, in particular the RSP, and thus purify the polluted air. The dust arrester is easy and economic to be operated, because no costly dust filtering screens or dust collecting bags are required and replacing / refilling water in the water trough is the only regular effort needed for continuous operation.

Problems solved by technology

It is well known that air pollution is becoming an increasingly serious problem.

A main source of air pollution is from construction and decoration projects in cities.

Due to the inherent nature of construction and decoration engineering and urgent schedule that often requires various kinds of operations to be carried out within a limited space in a short time, the work sites of construction and decoration engineering are generally full of dust and undesirable odors.

Therefore, not only the engineering staff at the working sites but also the neighboring residents will be exposed to and have to endure the poor environmental condition.

Even after the projects are completed, building materials will still release harmful gases and odor, especially volatile organic compounds (VOC) such as formaldehyde, for a long time.

These gases cannot be dispersed quickly in a natural way.

Moreover, the RSP can remain in the air for a long time in a large area ranging from several to hundreds kilometers because of its extremely light weight.

The maintenance is very inconvenient and also uneconomical, especially in areas where large amount of dust is generated or present.
